Resource [1.8] MoreProjectiles

Hey!
I created lib in which you can create more projectiles.

Right now there are 5 types of custom projectiles:

• ItemProjectile - extends EntityItem
• BlockProjectile - extends EntityFallingBlock
• OrbProjectile - extends EntityExperienceOrb (it's a little buggy)
• TNTProjectile - extends EntityTNTPrimed
• ProjectileScheduler - creates projectile from every possible entity passed as parameter in constructor(head rotation of mobs is a little bit bugged right now)

To spawn simple projectile just type something like this:

Code:

ItemProjectile projectile = new ItemProjectile("name", shooter, item, power);

It automagiclly gives velocity, position and direction from shooter to EntityItem and spawns it in world.
If you want to modify behavior of projectile when it hits something add this event:

Code:

    @EventHandler
    public void onHit(CustomProjectileHitEvent e){
        if (e.getHitType() == HitType.ENTITY){
            e.getHitEntity().damage(3D, e.getProjectile().getShooter());
        }
    }

If you want to play with some variables like velocity then get bukkit entity from projectile like this:

Code:

projectile.getEntity().setVelocity(velocity);

It uses DarkBladee12 's particle lib.

By creating projectiles from items, do you mean it shoots the itemdrop at the velocity/power that you specify (like launchProjectile(Item.class) would do) ?

Very nice though

 

Exactly, but it's not just Item. It's custom EntityItem, so I disabled picking up items and merging with other items, changed a little some despawn and added detecting colissions with blocks and entities, event when item hits something and some cool particles

 

Ahhh ok, even better! Will definitely be using this

 

Is this something that will break on updates?

I'm now watching this thread, as I'm sure I will want to use this some day.

 

Yes, it will break on updates :/ And becouse one class extends class from nms it would be hard to do it version proof. I'll try to update it as soon as any update will be.

 

Well then.. I'll be using this Thanks.

 

I'm glad someone found it useful

 

That's too bad. I wouldn't really want to rely on a library that has to be updated every mc-update. I'm guessing this kind of functionality will never be added to the API though, so that's a shame.

 

I'm also working on simple app which will replace packages in compiled jar for quick updating any plugin.

 

Ooh, nice. It would be even more awesome if it could check if the methods you use have changed (breaking your plugin), but I don't know if that's possible from a technical point of view.

 

No, it would be too difficult. Just checked it. That would be too perfect.

 

Add the ability to set the name of the projectile in the constructor, then get its name onProjectileHit!

So that you can differentiate between projectiles

 

Great idea, i'll add it tomorrow

 

Here, I added the ability to get the ItemStack from the event , and name the projectiles and get the name from the event. Few classes you need to update though

New class: ItemProjectileHitEvent.java Listen to this instead~! It extends CustomProjectileHitEvent, and has ability to get the ItemStack of the projectile

Code:java

 
import org.bukkit.Bukkit;
import org.bukkit.block.Block;
import org.bukkit.block.BlockFace;
import org.bukkit.entity.LivingEntity;
import org.bukkit.inventory.ItemStack;
 
import com.stirante.MoreProjectiles.projectile.CustomProjectile;
 
public class ItemProjectileHitEvent extends CustomProjectileHitEvent{
private ItemStack i;
public ItemProjectileHitEvent(CustomProjectile pro, Block b, BlockFace f, ItemStack i) {
super(pro, b, f);
this.i=i;
Bukkit.getServer().getPluginManager().callEvent(new CustomProjectileHitEvent(pro,b,f));
}
public ItemProjectileHitEvent(CustomProjectile pro, LivingEntity ent, ItemStack i) {
super(pro,ent);
Bukkit.getServer().getPluginManager().callEvent(new CustomProjectileHitEvent(pro,ent));
}
 
public ItemStack getItem(){
return i;
}
}

Now to spawn projectile, do:

Code:

new ItemProjectile("Grenade",player.getLocation(),new ItemStack(Material.SLIME_BALL),player);

And to listen for projectiles, do:

Code:

@EventHandler
public void onItemProjectileHit(ItemProjectileHitEvent e){
  if(e.getName().equals("Grenade"){
    //do stuff :)
  }
}

 

I added this, but I wrote it myself depending on your code. I don't have time for testing it. Also I added BlockProjectile which is falling block (and it's also not tested at all)

 

What does it implement the Particles class for?
And how can I get the hit location when it hits a block?

 

Particles class makes particles when projectile hits entity or block. To get location, do CustomProjectileHitEvent and if getHitType is HitType.BLOCK then do event.getBlock().getLocation(). You can also get block face hit by projectile.

Also i was thinking about xp orb projectile

 

Hi,
love this lib so much...

how about adding this to ItemProjectileHitEvent:

Code:java

 
public Block getHitBlock() {
    return block;
}
 
public Location getHitLocation() {
    Location l = null;
    if (getHitType() == HitType.ENTITY) {
        l = getHitEntity().getLocation();
    } else if (getHitType() == HitType.BLOCK) {
        l = getHitBlock().getLocation();
    }
    return l;
}
 

and i also would recommend to change the projectile identifier (i mean the name of a projectile) from String to a ItemStack...

 

In ItemProjectileHitEvent you have getItemStack() so no need for changing name to itemstack. Also if you want to get projectile's location do event.getProjectile().getEntity().getLocation().

 

hmm.. fuck .. you are right... in my modified version of your lib, i have a ItemStack, that has the ItemStack from the tool that triggered the projectile... but i dont thing about that you can use the libary without tools >.<

and yes, but my getHitLocation() returns the location of the target... event.getProjectile().getEntity().getLocation() returns the location of the entity.... there is a different...
for example if i use a arrow as projectile... and the arrow stucks in a block... the arrow is on another block (air) as the hitted block

 

michidk Haha, i just saw that i forgot to add getHitBlock() and getHitFace(). I added it now with new projectile type. I also added orb projectile from experience orb, but it's right now a bit buggy, becouse of delay after spawning it. To see it try spawning orb projectile straight into the air.

 

is there a way to make the projectile invulnerable?
cause my projectiles get destroyed by lava...

 

I can add it.

 

Made all events cancellable which cancels particles and keeps particle alive, cause I wanted to make it bounce when it hits ground Also added setInvulnerable and isInvulnerable. Orb projectiles still bugged, someone on irc told me that it's minecraft's bug, not bukkit so i can't fix it :/

 

update plz

 

Does this work with 1.6.4? Cause its giving me a error when i try to put the itemstack.

 

TrollTaylor michidk Sorry, I was in another country, i will asap update it.

 

TrollTaylor michidk Updated to 1.6.4 but still untested yet.

 

How do I make deal damage to an entity
